Description

Technical Field

[0001] This utility model relates to the field of wire rope flaw detection technology, and more specifically, to a wire rope flaw detector. Background Technology

[0002] As a lifting and transportation tool, wire ropes will wear out and develop internal defects after prolonged use, which may even lead to breakage accidents in severe cases, posing a great danger to workers and equipment. Wire rope flaw detectors can conduct comprehensive inspections of wire ropes, promptly detect and locate these defects, thereby ensuring the safe use of wire ropes.

[0003] For example, patent CN219871314U discloses a wire rope flaw detector device, including an upper body and a lower body disposed at the bottom of the upper body, as well as a locking assembly disposed on one side of the upper and lower bodies. An annular groove for the wire rope to pass through is provided between the upper and lower bodies. Although this wire rope flaw detector device is convenient to use and can be installed by one person, in actual use, the annular groove inevitably rubs against the wire rope. With repeated use, this causes wear on the annular groove. Furthermore, oil and other contaminants on the wire rope can make the annular groove unclean. If the contaminants in the annular groove are not treated in time, the reliability of the detection results will be affected. Therefore, improvements are needed. Summary of the Invention

[0004] The purpose of this invention is to provide a wire rope flaw detector to solve the problems mentioned in the background art.

Detailed Implementation

[0024] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are merely illustrative of this utility model and are not intended to limit it.

[0025] The following is in conjunction with the appendix Figures 1-7 This embodiment will be described in further detail.

[0026] Please see Figures 1-7 This embodiment of a wire rope flaw detector includes a flaw detector body, which comprises an upper body 100 and a lower body 101. An annular groove 102 for the wire rope to pass through is provided between the upper body 100 and the lower body 101. A detachable protective shell 103 is provided within the annular groove 102, with both ends of the protective shell 103 extending out of the annular groove 102. Fixing components are provided at both ends of the protective shell 103. Connecting components are symmetrically provided at both ends of the upper body 100 and the lower body 101. Block 104, the connecting block 104 is provided with a socket 105, the fixing component includes a plug rod 106 that can be inserted into or detached from the socket 105, the protective shell 103 is provided with a closing component at both ends for closing the two ends of the annular groove 102, the upper half body 100 and the lower half body 101 are connected on one side by a hinge 400, and the other side is detachably connected by a self-locking buckle 401, the upper half body 100 is provided with a handle 402, and a rotatable concave wheel 403 is provided at one end of the handle 402.

[0027] In this embodiment, the upper body 100 and the lower body 101 are opened by hinge 400 on one side. Thus, the annular groove 102 is divided into an upper part and a lower part, and the protective shell 103 is also divided into an upper part and a lower part. The upper part and the lower part of the protective shell 103 are respectively attached to the surfaces of the upper part and the lower part of the annular groove 102. When the wire rope is inspected, the self-locking buckle 401 can be released from the lock between the upper body 100 and the lower body 101, so that the upper body 100 and the lower body 101 are opened at a certain angle. Then, the wire rope is placed in the protective shell 103, and then the upper body 100 and the lower body 101 are closed by the self-locking buckle 401. Then, the handle 402 is held and guided by the concave wheel 403, so that the flaw detector body moves along the wire rope, and the wire rope can be inspected.

[0028] In this embodiment, the flaw detector body is an existing structure, which is equipped with flaw detection components inside. It uses the principle of magnetic leakage detection to perform flaw detection. If there is a defect in the steel wire rope passing through the annular groove 102, a magnetic leakage field or a change in magnetic flux will be generated on its surface. These changes are detected by the sensor, thereby determining the damage of the steel wire rope.

[0029] In this embodiment, the fixing component, connecting block 104, insertion hole 105 and insertion rod 106 are arranged so that the connecting block 104 is fixedly connected to the end faces of the upper half body 100 and the lower half body 101 respectively. The fixing component is fixedly connected to the protective shell 103, that is, the mounting block 201 is fixedly installed at the end of the protective shell 103. The insertion rod 106 is inserted into the insertion hole 105 so that the protective shell 103 can be fixed in the annular groove 102. When the wire rope is subjected to flaw detection, the protective shell 103 can protect the annular groove 102, avoid the wire rope from causing wear to the annular groove 102, and prevent oil and other pollutants from contaminating the annular groove 102.

[0030] In this embodiment, the protective shell 103 can be released from the annular groove 102 by disengaging the insertion rod 106 from the insertion hole 105. When the protective shell 103 is worn or needs to be cleaned, it can be removed for replacement and cleaning.

[0031] Specifically, the protective shell 103 can be made of plastic, and when it is installed in the annular groove 102, it will not interfere with the flaw detector body's flaw detection of the wire rope.

[0032] In this embodiment, by setting up the closing component, the two ends of the protective shell 103 can be closed when the wire rope flaw detector is not in use and is placed aside, so as to prevent dust and other foreign objects from entering the annular groove 102, causing pollution to the annular groove 102 and affecting its use.

[0033] Please see Figures 1-7In this embodiment, the fixing component also includes an extension block 200 connected to both ends of the protective shell 103. The extension block 200 is provided with a mounting block 201 for mounting the insertion rod 106. The mounting block 201 is provided with symmetrical non-communicating mounting cavities 202. Both ends of the mounting block 201 are provided with round holes that communicate with the corresponding mounting cavities 202. The open end of the round hole is threaded with a plug cap 203. The insertion rod 106 is located in the mounting cavity 202 and one end extends through the plug cap 203. The other end of the insertion rod 106 is provided with a push block 204. The mounting cavity 202 is provided with a spring 205 for pushing the push block 204 to drive the insertion rod 106 to insert into the insertion hole 105.

[0034] In this embodiment, the extension block 200, mounting block 201, mounting cavity 202, circular hole, plug 203, push block 204, and spring 205 are arranged to fix the extension block 200 to the protective shell 103, the mounting block 201 to the extension block 202, and the plug 203 to the opening of the circular hole, which facilitates the installation of the internal components of the mounting cavity 202. The push block 204 is fixedly connected to the insertion rod 106. When the protective shell 103 is installed, the upper body 100 and the lower body 101 can be opened first, and then the protective shell 103 can be embedded into the annular groove 102. The spring 205 pushes the push block 204, and the push block 204 pushes the insertion rod 106, which can drive the insertion rod 106 to be inserted into the insertion hole 105, thereby completing the fixed installation of the protective shell 103 in the annular groove 102.

[0035] Please see Figures 1-7 In this embodiment, the upper end face of the mounting block 201 is provided with a sliding cavity 206 that communicates with the corresponding mounting cavity 202. The surface of the insertion rod 106 is provided with a rod body 207 that extends out of the sliding cavity 206 and is used to drive the insertion rod 106 out of the insertion hole 105. The rod body 207 is provided with a pull block 208 for pulling the rod body 207.

[0036] In this embodiment, the sliding cavity 206, the rod 207, and the pull block 208 are arranged to fix the rod 207 and the insertion rod 106 together, and the pull block 208 is fixedly connected to the rod 207. When it is necessary to remove the protective shell 103, the upper half of the main body 100 and the lower half of the main body 101 can be opened first, and then the pull block 208 can be pulled. The pull block 208 drives the rod 207 to move along the sliding cavity 206. The rod 207 can drive the insertion rod 106 to disengage from the insertion hole 105, and the protective shell 103 can be removed from the annular groove 102.

[0037] Please see Figures 1-7 In this embodiment, the closing component includes a horizontal block 300 connected to the side of the mounting block 201. The horizontal block 300 is provided with a baffle 301 for closing the two ends of the annular groove 102 and is slidable. The horizontal block 300 is provided with a T-shaped groove, and the upper end of the baffle 301 is provided with a T-shaped block that extends into the T-shaped groove and slides.

[0038] In this embodiment, the horizontal block 300, the baffle 301, the T-slot, and the T-block are arranged to fix the horizontal block 300 to the mounting block 201. The T-slot is arranged along the length of the horizontal block 300. The baffle 301 is slidably connected to the horizontal block 300 by sliding the T-block in the T-slot. When the wire rope flaw detector is in use, the sliding baffle 301 opens the annular groove 102. When the wire rope flaw detector is not in use and is placed aside, the sliding baffle 301 closes the annular groove 102 to prevent dust and other foreign objects from entering the annular groove 102 and causing pollution.

[0039] Please see Figures 1-7 In this embodiment, the upper end face of the horizontal block 300 is provided with a groove 302 that communicates with the T-shaped groove, the upper end of the baffle 301 is provided with a limiting rod 303 extending from the groove 302, the two ends of the groove 302 are provided with limiting holes 304, and the limiting rod 303 is threaded with a nut 305 that can be inserted into the limiting hole 304.

[0040] In this embodiment, the groove 302, the limiting rod 303, the limiting hole 304, and the nut 305 are configured to fix the limiting rod 303 to the baffle 301. The nut 305 is threaded onto the limiting rod 303, allowing the nut 305 to move up and down along it. When the nut 305 moves upward and disengages from the limiting hole 304, the movement of the limiting rod 303 in the groove 302 can drive the baffle 301 to slide along the T-slot, thereby controlling the closure of the annular groove 102. When the annular groove 102 is completely closed or open, rotating the nut 305 causes it to move downward into the limiting hole 304, which can limit the baffle 301 and prevent it from sliding, causing the annular groove 102 to close or open. At the same time, it can prevent the baffle 301 from disengaging from the cross block 300 after the annular groove 102 is opened.

[0041] In use, when installing the protective shell 103 in the annular groove 102, the upper body 100 and the lower body 101 can be opened first, and the protective shell 103 can be embedded into the annular groove 102. Then, driven by the spring 205, the insertion rod 106 is inserted into the insertion hole 105, thus completing the fixed installation of the protective shell 103 in the annular groove 102. When the protective shell 103 is worn or needs cleaning, the upper body 100 and the lower body 101 can be opened first, and then the pull block 208 can be pulled to disengage the insertion rod 106 from the insertion hole 105, so that the protective shell 103 can be removed for replacement or cleaning.

[0042] In summary, the above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall fall within the scope of the patent of the present utility model.
